Ask her to come inside

She is very quick to take you up on that offer, rushing inside and immediately standing as close as she can to the nearest heat source available, where you then head off to chamge into something decent, when you return she then goes into more depth about the program, telling you that the reason her species got involved in the homestay program was to learn how to integrate into human society, as they felt it was best for there future as a species.

After which you offer you something to eat to help warm her up, of which she gladly accepts, asking for eggs in particular due to her carnivore diet, luckily there was plenty for her even after your breakfast, after a quick wipedown on the pan you used, you quickly scrambled her up some eggs and she sat down and ate it as you explained to her that you weren't exactly expecting any of this as you didn't sighn up any homestay program, and that this must be some form of mix up, however she was certainly more then welcome to stay as long as it took to clear this up.

After she got done eating the two of you help her get a place set up for her to sleep, not unpacking as neither of you expected this to last that long, until you called the number that Miia was given to communicate with the homestay agency, which resulted in the same lady that dropped her off very quick to say that she was 15 minutes away from her week long vacation, and that it was illegal to transfer a homestay's residency without her taking them to the house, and she was not willing to go back until after her vacation, so Miia was stuck inside the house until the week was over, after talking it over with her she unpacks her bags and gets aclimated to the house while you begin to do the rest of your tasks for the day
